Nature and UbjectsV of the Invention.

Our invention relatesvto the class oflocks usually appledtomoney-drawers under the counter of store, that is arranged to give analarm when the drawer :is

tampered-with by other persons than those connected 'with the store orconversant with the lock; and

It consists in such a construction and arrangement ofthe several partsof which the lock is composed that a variety of changes may be readilyand convenient-ly made in the tumblers that operate the catch, saidchange rendering'the lock susceptible of combinations that may be variedfrom time to time,

' as may be desired.

Description 'of the Accompanying Drawing.

Figure2 is a topjview of the lock, showing the catch raised up, toexpose the interior of the lock, the hinged or pivoted catchxB, beingalso shown detached. I

General Description.

The lock is composed of the cast-iron case or trainework A, hinged catchB, series of tumblers O, horizontal guide-plates, D, levers E, andpull-wire F, and is' attached to the drawer G, as shown. y

An alarm-bell, H, with apparatus arranged, milch in the usual manner,for operating the hammer, is atached to the counter or table-tcp I insuch a manner -that the catch B'will engage with the lever J and tripthe hammer K, to strike the bell.' The levers E, 'corresponding in,number with the number of tumblers O, 'are made with three arms, asshown, and arej pivoted on a longitudinal wire, E, at the bottom of thecase. The front and'rear arms of these levers E serve as arest for andthe means by which to operate the tnmhlers O. The tumbleis O are made inthe form shown, and'work loosely in holes in the guideplates D, andany-desired number of them may be used, with, ot' course, aVcorresponding number of levers and pnllwires. The rear arms ofl levers-E have a downward projecting point that engages with acorrespondingpoint projecting upward from the lower cross-bar of' the frame, whichserves as a stop to too great a movement of the levers, and they alsoserve to hold the spiral springs L in place.`

The springs L hold the levers- E, tumblers 0, and catch B in theposition shown in lign-1, so that the catch I will engage withlevers Jand return them to that position, when they have beendrawn down, bypulling the wires F. Any number of the tumblers Oless than the whole maybe turned around, asindicated by the dotted lines in fig. 1, "and, whenso turned, drop down too liu' to affect the hinged catch B. As onlythose tumhlers that rest on' the rear arm of level' E operate thefcatchB, it will be readily understood that various combinations may be madeto operate the 'catch by turning the tumblers around, and these may bevaried at pleasure, and'known only to those` using the drawer.

When theileversare operated to let the tnmblers down, the catch B dropsdown by its own gravity be- .low the lever J, when the drawer may bepulled out.

' 'lhe drawer is thrust forward, or rather held in such a position thatthe catch B rests against the lever J by means ot' the spring N, whichprevents the catch from dropping down until the drawer is pushed backalittle, to release the catch.

As a substitute for'the springs L the forward arm of levers E may beweighted, to bring them into the position shown.

Claims.

We claim as' our invention-.

1. The combination ot' the lthree a'rmed levers E, the reversibletumblers C, and catch B, when arranged substantially as set forth.

2. '.lhe combination of the springN and bell-lever J with -the hingedcatch B, all arranged substantially as and t'or the purpose set forth.OYRUS TUCKER.
